<h3 id="2-4框架组合"><a href="#2-4框架组合" class="headerlink" title="2.4框架组合"></a>2.4框架组合</h3><p>品优购采用当时(2017)流行的前后端编程架构。</p>
<p>后端框架采用Spring +SpringMVC+mybatis +Dubbox 。前端采用angularJS + Bootstrap。</p>
<h1 id="二、Dubbox框架"><a href="#二、Dubbox框架" class="headerlink" title="二、Dubbox框架"></a>二、Dubbox框架</h1><h2 id="1-Dubbox简介"><a href="#1-Dubbox简介" class="headerlink" title="1.Dubbox简介"></a>1.Dubbox简介</h2><p>Dubbox 是一个分布式服务框架，其前身是阿里巴巴开源项目Dubbo ，被国内电商及互联网项目中使用，后期阿里巴巴停止了该项目的维护，当当网便在Dubbo基础上进行优化，并继续维护，为了与原有的Dubbo区分，故将其命名为<strong>Dubbox</strong>。</p>
<p>Dubbox 致力于提供高性能和透明化的RPC远程服务调用方案，以及SOA服务治理方案。简单的说，dubbox就是个服务框架，如果没有分布式的需求，其实是不需要用的，只有在分布式的时候，才有dubbox这样的分布式服务框架的需求，并且本质上是个服务调用的东东，说白了就是个远程服务调用的分布式框架。</p>

<p><strong>节点角色说明：</strong></p>
<p>Provider: 暴露服务的服务提供方。</p>
<p>Consumer: 调用远程服务的服务消费方。</p>
<p>Registry: 服务注册与发现的注册中心。</p>
<p>Monitor: 统计服务的调用次调和调用时间的监控中心。</p>
<p>Container: 服务运行容器。</p>
<p><strong>调用关系说明：</strong></p>
<ol>
<li><p>服务容器负责启动，加载，运行服务提供者。</p>
</li>
<li><p>服务提供者在启动时，向注册中心注册自己提供的服务。</p>
</li>
<li><p>服务消费者在启动时，向注册中心订阅自己所需的服务。</p>
</li>
<li><p>注册中心返回服务提供者地址列表给消费者，如果有变更，注册中心将基于长连接推送变更数据给消费者。</p>
</li>
<li><p>服务消费者，从提供者地址列表中，基于软负载均衡算法，选一台提供者进行调用，如果调用失败，再选另一台调用。</p>
</li>
<li><p>服务消费者和提供者，在内存中累计调用次数和调用时间，定时每分钟发送一次统计数据到监控中心。</p>
</li>
</ol>
<h2 id="2-注册中心Zookeeper"><a href="#2-注册中心Zookeeper" class="headerlink" title="2.注册中心Zookeeper"></a>2.注册中心Zookeeper</h2><p>Zookeeper在之前<a target="_blank" rel="noopener" href="https://jy741.cn/2020/06/13/305.html">solr集群</a>的时候已经详细介绍了它的一种使用方法——集群管理，这里就简短说明，不做过多赘述。</p>
<h3 id="2-1Zookeeper介绍"><a href="#2-1Zookeeper介绍" class="headerlink" title="2.1Zookeeper介绍"></a>2.1Zookeeper介绍</h3><p>官方推荐使用 zookeeper 注册中心。注册中心负责服务地址的注册与查找，相当于目录服务，服务提供者和消费者只在启动时与注册中心交互，注册中心不转发请求，压力较小。</p>
<p>Zookeeper 是 Apacahe Hadoop 的子项目，是一个树型的目录服务，支持变更推送，适合作为Dubbox 服务的注册中心，工业强度较高，可用于生产环境。</p>
<h3 id="2-2Linux安装zookeeper"><a href="#2-2Linux安装zookeeper" class="headerlink" title="2.2Linux安装zookeeper"></a>2.2Linux安装zookeeper</h3><p>这里具体安装在之前博客中也有详细介绍，这里说一下大体过程。</p>
<p>环境：安装 jdk</p>
<p>把 zookeeper 的压缩包上传到linux服务器；解压缩压缩包；进入目录，创建 data 文件夹；进入conf目录 ，把 zoo_sample.cfg 改名为 zoo.cfg；打开zoo.cfg , 修改 data 属性：dataDir=/root/zookeeper-3.4.6/data；进入bin目录，启动服务输入命令。</p>

<p>我们现在需要手动将Dubbox的jar包安装到我的本地仓库中。</p>
<p>先将dubbo-2.8.4.jar包放到d:\setup(位置随意), 然后输入命令</p>

<p>在pom文件加入dubbox依赖</p>
<p><strong>注意：Service注解与原来不同，需要引入com.alibaba包下的</strong></p>
<blockquote>
<p>import com.alibaba.dubbo.config.annotation.Service;</p>
</blockquote>
<p>在applicationContext-service.xml 原本基础上加上</p>
<pre class="line-numbers language-markup" data-language="markup"><code class="language-markup"><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span><span class="token namespace">dubbo:</span>application</span> <span class="token attr-name">name</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>dubboxdemo-service<span class="token punctuation">"</span></span><span class="token punctuation">/&gt;</span></span>

<p>注意：dubbo:annotation用于扫描@Service注解。</p>
<h3 id="3-2服务消费者开发"><a href="#3-2服务消费者开发" class="headerlink" title="3.2服务消费者开发"></a>3.2服务消费者开发</h3><p>跟上面差不多，不过在Controller层引用Service时由于是不同的系统，跨系统我们用到dubbox给我们提供的Reference注解</p>
<pre class="line-numbers language-java" data-language="java"><code class="language-java"><span class="token annotation punctuation">@Reference</span>

<h2 id="4-管理中心的部署"><a href="#4-管理中心的部署" class="headerlink" title="4.管理中心的部署"></a>4.管理中心的部署</h2><p>我们在开发时，需要知道注册中心都注册了哪些服务，以便我们开发和测试。我们可以通过部署一个管理中心来实现。其实管理中心就是一个web应用，部署到tomcat即可。</p>
<h3 id="4-1管理端安装"><a href="#4-1管理端安装" class="headerlink" title="4.1管理端安装"></a>4.1管理端安装</h3><p>（1）编译源码，得到war包</p>
<p>资源中有个dubbox-master.zip ，这个是dubbox的源码，我们可以使用maven命令编译源码得到“管理端”的war包</p>
<p>在命令符下进入dubbo-admin目录 ，输入maven命令</p>
<pre class="line-numbers language-bash" data-language="bash"><code class="language-bash">mvn package -Dmaven.skip.test<span class="token operator">=</span>true<span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>

<p>（2）进入target文件夹，你会看到一个dubbo-admin-2.8.4.war ， 在linux服务器上安装tomcat, 将此war包上传到linux服务器的tomcat的webapps下。为了访问方便，你可以把版本号去掉。 启动tomcat后自动解压。</p>

<p>这里给出模块简介。</p>
<p>父工程：pinyougou-parent（POM）</p>
<p>通用实体类模块：pinyougou-pojo（jar）</p>

<h2 id="2-逆向工程"><a href="#2-逆向工程" class="headerlink" title="2.逆向工程"></a>2.逆向工程</h2><p>这里我们通过逆向工程实现实体类与数据访问层代码的自动生成。</p>
<p>将com.pinyougou.pojo包拷贝到pojo工程</p>
<p>将com.pinyougou.mapper包和resouce下的com.pinyougou.mapper文件夹拷贝到dao工程</p>
<p>同时为了满足网络传输，修改每个实体类，让其实现Serializable接口。</p>
